[rules-users] Introduction to my project

[Ellen Zhao]

Hi Ari,

just read your problem description and I guess optimizing the solution
with some evolutionary / genetic algorithms would be better off than
using Rete-based algorithms. You can have a look at the Drools-Solver
documentation.

You can implement the algorithm as some service provider and put them
in session beans. If your project is not a "legacy" project, try out
JEE 5 compliant application servers. Wiring a bunch of JEE 5 session
beans is easier than wiring the same amount of J2EE session beans.


Best Regards,
Ellen
